At Surfside, 20- and 30-somethings gather on the rooftop deck to sip margaritas and dive into guacamole, while down in the colorful and casual eatery, their married-with-children peers, families in tow (and yes, there’s a kid’s menu), nosh on tacos, quesadillas, burritos, and salads. Surfside is especially known for its fresh grilled fish tacos, but its menu covers assorted options, including a pork carnitas taco served with pineapple jalapeño salsa on corn tortillas, that I like. But if the menu combinations don’t appeal, you fill out a form indicating your desired ingredients so the cook can custom-prepare your order. Technically, Surfside is in a neighborhood called Glover Park, which is just north of Georgetown, so not far. Good to know: Surfside does a brisk takeout business, too, and it operates a 24-hour taco stand at 1800 N St. NW (202/466-1830), at Connecticut Ave. NW, in the Dupont Circle neighborhood.
